Layer.OSM.Mapnik is a tiled layer, there are no features on it.
Features are on vector layers (OpenLayers.Layer.Vector,
OpenLayers.Layer.GML, OpenLayers.Layer.WFS).

If you have a line in your code like:

var layer = new OpenLayers.Layer.Vector("my vector layer");

then you can configure your DragFeature control with

var dragfeature = new OpenLayers.Control.DragFeature(layer);

Maybe I should have said "instance" instead of "object", then things
would have been clearer in the first place.

Regards,
Andreas.
